ABSTRACT:
A signal acquisition probing system uses a micro-cavity laser to acquire an electrical signal from a device under test. The micro-cavity laser has VCSEL gain mediums and an electro-optic optical resonant cavity. The micro-cavity laser is pumped by an external laser source and generates polarized frequency modulated optical signals derived from the device under test electrical signal creating an electro-magnetic field distribution in electro-optic material in the micro-cavity laser that overlaps the optical path of the polarized optical signals propagating in the electro-optic material. The polarized frequency modulated optical signals are coupled to an optical receiver which converts the polarized frequency modulated optical signals to an electrical signal. The electrical signal is coupled to measurement test instrument for processing and displaying of the electrical signal.
